We divide 85351581 by 317
We want to figure out the number of times 85351581 can be divided by 317.

On to step 1:
When dividing 8 by 317, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 317

Let's proceed to step 2:
When dividing 85 by 317, we get 0 with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Include the next digit (3) from the dividend after 85, then repeat: 853 / 317

Going ahead to step 3:
The number 317 fits into 853 2 times, leaving a remainder of 219.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 634 from 853, we get 219.
Take the next digit (5) from the dividend and append it to 219, then repeat: 2195 / 317

Advancing to step 4:
317 goes into 2195 6 times with a remainder of 293.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Subtracting 1902 from 2195 leaves us with 293.
Append the next digit (1) from the dividend to 293 and continue with: 2931 / 317

Moving on to step 5:
If we divide 2931 by 317, we get 9 and a remainder of 78.
The number 9 becomes the next digit in our result. 
Result so far: 269.0
If we subtract 2853 from 2931, we get 78.
Append the next digit (5) from the dividend to 78 and continue with: 785 / 317

Going ahead to step 6:
When dividing 785 by 317, we get 2 with a remainder of 151.
The number 2 becomes the next digit in our result. 
Result so far: 2692.0
Subtracting 634 from 785 leaves us with 151.
Bring next digit (8) of the dividend behind the 151 and repeat the process: 1518 / 317

Going ahead to step 7:
The number 317 fits into 1518 4 times, leaving a remainder of 250.
Write down 4 as next digit of the result. 
Result so far: 26924.0
Subtract 1268 from 1518 to get 250.
Grab the next digit (1) from the dividend, add it to 250, then carry on: 2501 / 317

Going ahead to step 8:
2501 divided by 317 is 7 with a remainder of 282.
Write down 7 as next digit of the result. 
Result so far: 269247.0
If we subtract 2219 from 2501, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

On to step 9:
When dividing 2820 by 317, we get 8 with a remainder of 284.
The next digit of our result is 8. 
Result so far: 269247.8
Subtract 2536 from 2820 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 10:
317 can be fit into 2840 8 times, resulting in a remainder of 304.
Record the quotient 8 as the next digit in the result. 
Result so far: 269247.88
The remainder is 304 after subtracting 2536 from 2840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

The quotient of the division is 269247.88, and the remainder is 0.304.
